Modulated Continuous Wave Control for Energy-efficient Electron-nuclear Spin Coupling

Abstract

We develop energy efficient, continuous microwave schemes to couple electron and nuclear spins, using phase or amplitude modulation to bridge their frequency difference. These controls have promising applications in biological systems, where microwave power should be limited, as well as in situations with high Larmor frequencies due to large magnetic fields and nuclear magnetic moments. These include nanoscale NMR where high magnetic fields achieves enhanced thermal nuclear polarisation and larger chemical shifts. Our controls are also suitable for quantum information processors and nuclear polarisation schemes.
